Got all of the models shown there too - except the Lupo and the Skycat.

I even have two Twisters - a grey one and white one.

Not sure what the plan is yet........

Correct.

Some models just never appealed to me or triggered an interest.

I just stumbled over one of his other videos:

Flying under Stockholm (5 min 57 sec)


Apart from that my "extinct" TwinJet is coming together. But since I got from somebodys grandparents closet, it still has a certain smell of cigar smoke clinging to the foam (despite being washed with warm water and soap), and all but the foam is missing. I easily located a 10x10mm balsa keel, but it will have to do without the inner fuse tub.

Since the was a small damage to one elevon, I took the opportunity to add small, wooden reinforcement to elevons and vertical stabs. Since balsa is used for the keel, it felt right to use also wood reinforcements. Avoiding CF may also help radio reception.

Elevon during gluing:


Vertical stabs, one side w painted reinforcement:


Motors and ESC (Flush mounted) done:


close up:


Since I just obtained the foam parts, I miss a pair of the original, T-shaped rudder horns from MPX. Shipping for these alone is $14 + $12 for the parts bag, so if anybody has a spare set lying around it would be great....

You can use much more aggressive stuff on Elapor than water and soap. Give it a wipe with acetone and the smell should be gone.

Using some carbon fiber tube imbedded in the inner walls of the fuselage should provide more strength and less weight than the ABS tub.

Don't worry about the use of carbon fibre. As long you don't have the complete structure covered with it, it is no problem regarding RC reception. Most EPP models use a lot of CFP for stiffening.

FlyingKiwi22,

thanks - and yes, I'm pretty hooked. Buying and flying my first RC plane almost exactly a year ago, the hangar now consists of (in order of appearance):

Multiplex TwinStar2
AXN FloaterJet
Multiplex PicoCub
Multiplex MiniMag
(Scratchbuild canard foamie 1, dead due to CoG problems)
Scratchbuild 250gr foamie 2
Scratchbuild 350gr Sopwith Camel foamie (flown, but under repair now)
Multiplex EasyStar 2
Multiplex Merlin
Multiplex Easystar 1 (build as an "EasyTwin" FPV platform)
Multiplex FunJet
Multiplex EasyStar 1 - light build
Multiplex Sonic Liner
Multiplex TwinJet (under construction)


I'm wondering what my next plane will be. Perhaps an EasyGliderPro? But I should start applying a one-out, one-in principle before I drown.... But what should go then?... hmmm...

Thanks - I would never have dared using acetone. Is there any common cleaner/stuff (alcohol/gas/petroleum/etc) that the Elapor will not tolerate?

I will imbed a couple of CF spars inside the fuse near the assembly point, and I also used a couple of 1x3mm CFs on the inner, trailing wing edge. You can see them as narrow black lines through the nacelles. Also did this on my Sonic Liner.

Alcohol is fine.

I have never tried Nutella. That might do a number on Elapor...mostly on account of the subsequent gnawing.

Nutella - hahaha - that made me laugh all right

Hate to spoil this nice "which one do want the most" thread with TwinJet build questions, but it seems all the old threads are too old for posting anything in, so here goes:

My TJ is coming together. Electronics done (newish one ESC BEC supply to one servo, and then dual 22ohm gating for Rx supply), mixing done, paint done. Just awaiting rudder horns and gluing verical stabs. Now this is where I get worried; From experience with my smaller FunJet, I know that the stabs easily get caught in the trunk of my car and in the doorways of the house. Would it be possible to use neodymium magnets to hold them in place, but letting them detach for transport or crashes? Or are the forces working on them in flight too great?



Oh, and to get back to topic. Someone mentioned wanting Multiplex to make a new TwinJet in a larger scale. I'm lining up behind him to get one!

thanks

Thank you, Dave!

I couldn't wait. Unwrapped and fit the things together. Nothing is missing. Just a servo arm is broken.

First thing to do is give the outer surface of the airframe a nice clean before applying the livery. It has nicotine stain from storage and marks of decals, which I all need to remove and render it nice plain white once again.
Next, I need to reinforce the fuse with some carbon, and possibly slightly modify the motor shells to accept the brushless inrunners.
A nice project to come, indeed.
